how to transform and plot trigonometric functions

Please explain how to approach the transformation of trigonometric functions

Doug C.

Read the notes (and take some notes) in this Desmos graph, then use the sliders on A,B,C,D (at the bottom of list) to see the effect changes have on the parent function. Right now the parent function is set to f(x) = sin(x) but you can change that (does not even have to be a trig function). For trig functions the value of C, when B = 1), causes a phase shift. This is also called horizontal shift. desmos.com/calculator/fzgjxyzpgd The value of B affects the period and is also called horizontal stretch or shrink. Once you have at least an idea of what is going on, come back with specific questions.

I would approach them carefully with a pencil and paper.
